The most promising current parallel BVH construction approach is to use a so-called linear BVH (LBVH). The idea is to simplify the problem by first choosing the order in which the leaf nodes (each corresponding to one object) appear in the tree, and then generating the internal nodes in a way that respects this … See more One of the great things about LBVH is that once we have fixed the order of the leaf nodes, we can think of each internal node as just a linear range … See more The algorithm just described (Garanzha et al.) is surprisingly fast when there are millions of objects. The algorithm spends most of the execution … See more Now that we have a hierarchy of nodes in place, the only thing left to do is to assign a conservative bounding box for each of them. The approach I adopt in my paper is to do a parallel bottom-up reduction, where each thread … See more There is no way to avoid this problem without somehow changing the algorithm in a fundamental way. Even if our GPU supports dynamic parallelism (as NVIDIA Tesla K20 does), we … See more WebBoth the BVH construction and ray traversal are easily implemented on GPUs and integrated into a GPU-based micropolygon renderer. In our experiments, our ray tracer performs up to an order of magnitude faster than the state-of-art rasterizers while consistently delivering an image quality equivalent to a maximumquality rasterizer.
